各位高手大家帮帮我的忙呀,我是刚学C++的,学得不怎么好,但是老师又要我们交一篇课程设计,是用C++做计算器,我做不出来,请大家帮帮我的忙呀,我们这周周五就要交了呀,先谢谢大家了呀!

这个是我仿照做的，你最好把其中一些东西修改一下，主要代码如下，这些代码都是在Dlg。cpp文件中：
int math_i;
double count=10;
char buffer[10];
double input_int=0,input_dec=0;
double input1=0,input2=0;
bool decimal=FALSE;
double value=0;
以上为全局变量：
在OnInitDialog()函数中添加如下代码：
m_Operator.AddString("加");
m_Operator.AddString("减");
m_Operator.AddString("乘");
m_Operator.AddString("除");
其他函数代码如下：
void CCaculator2Dlg::On1Button()
{
// TODO: Add your control notification handler code here
if(decimal)
{
input_dec=input_dec+1/count;
count=count*10;
}
else input_int=input_int*10+1;
input1=input_int+input_dec;
value=input1;
_gcvt(value,15,buffer);
m_EditResult=(LPCTSTR)buffer;
UpdateData(FALSE);
}

void CCaculator2Dlg::On0Button()
{
// TODO: Add your control notification handler code here
if(decimal)
{
input_dec=input_dec+0/count;
count=count*10;
}
else
{
input_int=input_int*10+0;
}
input1=input_int+input_dec;
value=input1;
_gcvt(value,15,buffer);
m_EditResult=(LPCTSTR)buffer;
UpdateData(FALSE);
}

void CCaculator2Dlg::On2Button()
{
// TODO: Add your control notification handler code here
if(decimal)
{
input_dec=input_dec+2/count;
count=count*10;
}
else input_int=input_int*10+2;

}

value=input1;
_gcvt(value,15,buffer);
m_EditResult=(LPCTSTR)buffer;
UpdateData(FALSE);

}

void CCaculator2Dlg::On5Button()
{
// TODO: Add your control notification handler code here
if(decimal)
{
input_dec=input_dec+5/count;
count=count*10;
}
else input_int=input_int*10+5;
input1=input_int+input_dec;
value=input1;
_gcvt(value,15,buffer);
m_EditResult=(LPCTSTR)buffer;
UpdateData(FALSE);

}

void CCaculator2Dlg::On6Button()
{
// TODO: Add your control notification handler code here
if(decimal)
{
input_dec=input_dec+6/count;
count=count*10;
}
else input_int=input_int*10+6;

}

{

if(decimal)
{

}

{

if(decimal)
{

count=count*10;
}
else input_int=input_int*10+8;
input1=input_int+input_dec;
value=input1;
_gcvt(value,15,buffer);
m_EditResult=(LPCTSTR)buffer;
UpdateData(FALSE);

}

void CCaculator2Dlg::On9Button()
{
// TODO: Add your control notification handler code here
if(decimal)
{
input_dec=input_dec+9/count;
count=count*10;
}
else input_int=input_int*10+9;
input1=input_int+input_dec;
value=input1;
_gcvt(value,15,buffer);
m_EditResult=(LPCTSTR)buffer;
UpdateData(FALSE);

}

void CCaculator2Dlg::OnDecimalButton()
{
// TODO: Add your control notification handler code here
decimal=TRUE;

}

void CCaculator2Dlg::OnSelchangeOperatorList()
{
// TODO: Add your control notification handler code here
//input1=input_int+input_dec;
decimal=FALSE;
input_int=0;
input_dec=0;
count=10;
math_i=m_Operator.GetCurSel();

}

void CCaculator2Dlg::OnEqualButton()
{
// TODO: Add your control notification handler code here
//UpdateData(TRUE);
input2=input_int+input_dec;
decimal=FALSE;
input_int=0;
input_dec=0;
count=10;
switch(math_i)
{
case 0:
value=input1+input2;
break;
case 1:
value=input1-input2;
break;
case 2:
value=input1*input2;
break;
case 3:
value=input1/input2;
break;
}
_gcvt(value,15,buffer);
m_EditResult=(LPCTSTR)buffer;
UpdateData(FALSE);
}
你需要的地方你修改一下吧。

我试一下,看整个文件能传上来吗?

[URL=E:\我的文件\c++源文件\练习\caculator2.rar]E:\我的文件\c++源文件\练习\caculator2.rar[/URL]

我再试一下,看整个文件能传上来吗?

[URL=caculator2.rar]caculator2.rar[/URL]

呵呵,传不上来.

````樓上在搞什麼?````點上靣的囬復主題```就能上傳叻```

我已经把代码复制到上面了,我试一下,能不能把整个文件用压缩包的形式传上来,但不行呀!

圖片上的囬復主題,就可以像髮帖子一樣加附件叻````
